N-Chlorsulfonyl-N-ethyl-urethan, also known as 1-chloro-N-ethyl-N-sulfonylurea or CESU, is an organosulfur compound with the chemical formula C3H7ClN2O2S. It is a colorless, crystalline solid that is soluble in water and organic solvents. CESU is primarily used as a chlorinating agent in organic synthesis, particularly for the preparation of chloroalkyl compounds and chloroalkylamines. It is also employed as a reagent in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. Due to its reactivity and potential hazards, CESU should be handled with caution, using appropriate safety measures and personal protective equipment.

2204-79-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2204-79-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,0 and 4 respectively; the second part has 2 digits, 7 and 9 respectively.Calculate Digit Verification of CAS Registry Number 2204-79:
(6*2)+(5*2)+(4*0)+(3*4)+(2*7)+(1*9)=57
57 % 10 = 7
So 2204-79-7 is a valid CAS Registry Number.
